Japan came a little late to the Twitter party, but it has quickly made up for lost time.  And it's not just individual users that have been fueling the Twitter boom.  Forward-thinking Japanese companies have also embraced the micro-blogging revolution in a big way, by developing Twitter marketing campaigns, offering Twi-wari discounts, incorporating Twitter into social games, and mining Twitter for valuable customer feedback.

The latest Japanese practice to be Twitterized is the fine art of tachiyomi (立ち読み) – browsing comics and magazines for free before you purchase them.

Tachiyomi, which literally means “stand and read,” can be observed 24/7 at one of the over 40,000 convenience stores or many of the bookstores in Japan. Most stores will allow customers to stand in front of the magazine rack and read through the comics with impunity.
